Security update for xen

This update for xen to version 4.7.2 fixes the following issues:

These security issues were fixed:

  • CVE-2017-7228: Broken check in memory_exchange() permited PV guest breakout (bsc#1030442).
  • XSA-206: Unprivileged guests issuing writes to xenstore were able to stall progress of the control domain or driver domain, possibly leading to a Denial of Service (DoS) of the entire host (bsc#1030144).
  • CVE-2017-6505: The ohci_service_ed_list function in hw/usb/hcd-ohci.c allowed local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors (bsc#1028235).

These non-security issues were fixed:

  • bsc#1015348: libvirtd didn't not start during boot
  • bsc#1014136: kdump couldn't dump a kernel on SLES12-SP2 with Xen hypervisor.
  • bsc#1026236: Fixed paravirtualized performance
  • bsc#1022555: Timeout in 'execution of /etc/xen/scripts/block add'
  • bsc#1029827: Forward port xenstored
  • bsc#1029128: Make xen to really produce xen.efi with gcc48

The ohci_service_ed_list function in hw/usb/hcd-ohci.c in QEMU (aka Quick Emulator) before 2.9.0 allows local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors, a different vulnerability than CVE-2017-9330.

Описание

An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the caller to drive hypervisor memory accesses outside of the guest provided input/output arrays.
